Description

Abstract class for coordinate transformations.

A single abstract base class is defined which will further be extended by its subclasses. The two main types of coordinate transformations are those represented by an analytic transformation and those represented by a discrete transformation. The coordinate transformation always transforms from a cartesian space in the logical variables \( \eta_1, \eta_2 \), ... to a physical space of variables \( x_1, x_2 \), ... For example, the 2D case represents the transformation:

\[ \begin{matrix} x_1 = x_1(\eta_1,\eta_2) \\\\ x_2 = x_2(\eta_1,\eta_2) \end{matrix} \]

The base class contains all the services (in the form of functions) that the different 'flavors' of coordinate transformations (analytic, discrete) should implement.
